  Normal switching should be at about 0.45v and slow switching is normal as it is just correcting the pre cat sensor. You may see an increase in gas mileage, but a post cat sensor rarely causes driveability issues unless they are shorted to ground.

How do you troubleshoot code p0058 ?

NOTE #1: It should be noted that code P0058 indicates a fault in the oxygen sensors’ heating control circuits, rather than issues with fuel/air metering. In cases where codes relating to fuel/air metering are present along with P0058, these codes must be resolved before starting an electrical diagnosis of code P0058.

NOTE #2: At the risk of overstating the case, code P0058 relates to oxygen sensors that are located after the catalytic converter.

NOTE #3: Check for, and repair all exhaust leaks before starting an electrical diagnosis of code P0058. Exhaust leaks can contaminate the atmospheric air used by oxygen sensors, which contamination can result in inaccurate readings.

How do you troubleshoot code p0157 ?

Circuit “High” and circuit “Low” DTCs are set when the ECM detects sensor voltage outside of what the sensor is physically capable of sending. For example, a certain HO2S may only signal between 0.1 V and 0.9 V, higher voltage signaling lower O2 content, and vice-versa.

If the ECM detects lower than 0.1 V or higher than 0.9 V, which the sensor cannot do, this means that there is a problem in the circuit or in the sensor itself. Depending on the vehicle, this voltage threshold may be different, so check your repair manual to be sure. You’ll need a DMM (digital multimeter) to diagnose the HO2S circuit.

• General Checks – First, check fuses and harnesses for any obvious problems, such as blown fuses and chafed or pinched wires. Check the oxygen sensors for damage. Check the connectors for bent or broken pins or corrosion and that they are properly seated. Repair as necessary.
• Exhaust Check – As a matter of course, use an open mechanic’s stethoscope to check for exhaust leaks, particularly between the TWC and HO2S. Repair as necessary.
• Circuit Checks – Disconnect the ECM and HO2S. Check for continuity on the two lines. You should have less than 1 Ω resistance end to end and more than 10 kΩ between them and to ground.
  • If you find excessive resistance or a short circuit, repair as necessary.
  • If resistance is proper, replace the sensor.
• Sensor – Generally, most people simply jump to replacing the sensor, though you shouldn’t condemn the sensor unless you can rule out circuit problems.

Step 1

Record all fault codes and available freeze frame data. This data can be useful in cases where an intermittent fault is diagnosed later on.

Step 2

Perform a thorough visual inspection of all associated wiring and connectors. Look for damaged, shorted, burnt, or broken wiring and connectors. Replace wiring and/or connectors as required, and rescan the system to see if the code returns.

NOTE: On some applications, the input voltage is supplied through a fused circuit. Be sure to check associated fuses during the initial inspection of the wiring.

Step 4

While the oxygen sensor is removed from the system, inspect the element for signs of discoloration, or the presence of deposits. Some aftermarket fuel and oil additives contain silicone-based compounds that can cause deposits to form on spark plugs and oxygen sensors.

What are the common causes of code p0058 ?

Common causes of code P0058 include the following-

Note that vacuum leaks that cause unmetered air to enter the engine are more likely to cause Oxygen Sensor Range/Performance issues than high input voltages in the control circuit.

What are the common causes of code p0157 ?

Depending on year, make, and model, DTC P0157 may have number of causes. Here are some of the most common.

• HO2S Fault – The most common failure is a fault in the sensor itself. Constantly exposed to the elements and to the heat of exhaust, HO2S has a typical lifespan of less than 5 years.
• Circuit Fault – Because they are exposed to the elements, wire harnesses, connectors, and the sensor itself may be physically damaged by impact or road debris. Water entry and corrosion are common faults.

What are the symptoms of code p0050?

In theory, a failed O2 heater will result in poor fuel economy. But you’ll probably never notice the difference during operation. The only thing you will notice is an illuminated check engine light on your dashboard. If your registration is due, you will also fail the emissions test.

What are the symptoms of code p0058 ?

While the symptoms of code P0058 are much the same on all vehicles, the severity of one or more symptoms may differ from vehicle to vehicle. Typical symptoms include the following-

• Rich-running condition
• Lean-running condition
• Increased fuel consumption
• Loss of power
• Rough idling
• Visible black smoke from the tail pipe
• Hard starting in some cases
• Illuminated CHECK ENGINE light
• Stored trouble code(s)

What are the symptoms of code p0157 ?

It does one good to note that the HO2S have nothing at all to do with fuel trim and are used only to verify TWC function, though FT problems, such as those caused by fuel pressure or misfiring cylinders, could skew HO2S readings, perhaps even set TWC or HO2S DTCs, but these would not result in circuit DTCs.

What does code p0157 mean?

The internal combustion engine ignites a hydrocarbon (HC) fuel, combining it with oxygen (O2), using the resulting energy output to turn the engine. The exhaust stream, ideally, is composed simply of water (H2O), carbon dioxide (CO2), and unreacted nitrogen (N2).

Unfortunately, due to inconsistencies in engine operation, air and fuel temperature, fuel composition, and a number of other factors, exhaust chemistry can be far from ideal. Excessive cylinder temperatures, for example, can lead to the production of nitrogen oxides (NO and NO2).

An excessively-rich air-fuel-ratio (AFR) can lead to elevated levels of unburned HC. Other conditions can lead to the production of carbon monoxide (CO), ozone (O3), and PM10 and PM2.5 (particulate matter less than 10 µm or 2.5 µm in size).

To reduce these combustion emissions, the engine control module (ECM) monitors air and fuel temperature, intake air mass and flow, combustion pressure, engine speed and load, and more to fine-tune AFR, valve timing and lift, spark timing, and others.

Still, even these controls are not enough to prevent some harmful emissions from forming, so the last step is the three-way catalytic converter (TWC or “Cat”), a chemical filter of a sort, that recombines harmful emissions into safer compounds. Unburned HC and PM2.

5 and PM10 emissions combine with CO, O3, O2 to produce H2O and CO2. The ECM compares oxygen sensor readings before and after the TWC to monitor its performance.

The AFR sensor, before the TWC, is used mainly as feedback to fine-tune fuel trim (FT), but also is used by the ECM to test the TWC. Under typical operation, the ECM increased and decreases FT, always attempting to zero in on 14.7:1 AFR, using the AFR sensors to verify.

Normal AFR sensor readings typically fluctuate high/low a few times a second. If the TWC is functioning properly, the heated oxygen sensors (HO2S) will barely fluctuate at all. Every few seconds, the ECM will force FT higher or lower than normal, which the AFR sensors will react to by showing higher or lower voltage than normal.

If the TWC is functioning properly, the downstream HO2S should barely react. If the HO2S voltage peaks at the same time as the AFR sensor voltage, this ECM determines that the TWC is not functioning properly and sets a DTC (diagnostic trouble code) related to TWC function.

Before the ECM can monitor the TWC, however, it needs to confirm that the AFR and HO2S are functioning properly, so it checks the heater and signal circuits for proper voltage and resistance. If the ECM detects signal voltage higher or lower than possible, it will illuminate the malfunction indicator lamp (MIL) and store a DTC in system memory, defined as follows:

• DTC P0157 Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 2 Sensor 2 (B2S2)

For reference, Bank 1 and Bank 2 refer to which bank of cylinders, left or right if it’s a V configuration, Bank 1 containing Cylinder 1. Inline engines may be divided, Bank 1 being Cylinder 1 & 2 or 1 – 3. Sensor 1 or Sensor 2 refers to the sensor’s position before or after the TWC. Sensor 1 is before the TWC and Sensor 2 is after the TWC.

Лямбда зонд. кислородный датчик, замена. аналоги. (с. 57) – ford focus 2

Добрый вечер, Podvodnik1

Поменял по твоим рекомендациям первый ЛЗ с финисом 0258006569, доработал его и “вошел” как к себе домой, еще раз спасибо за совет! Чек не погас, НО при этом расход стал меньше и это меня очень порадовало. Покатался пару дней и выявил через диагноста следующие ошибки:

Р0036 HO2S Heater Control CirCuit (Bank 1, Sensor 2)

P0136 O2 Circuit (Bank 1, Sensor 2)

единственное что я понял из этих ошибок – проблема в зонде который после каталлизатора идет, т.е. второй ЛЗ. Если я не прав, пожалуйста, поправь меня.

В случаи замены второго зонда, финис 0258006569 так же подойдет на мой авто? (1,6 100 л.с.)

Что-то я не хрена не понимаю. История такая – два года назад, зимой вылетел чек, поехал к диллеру они сделали диагностику и вынесли вердикт – лямда под замену. Код ошибки Р0037. Чек они потушили но сказали, что скоро опять загорится и не обманули, через недели две чек снова вылетел причем во время езды. Машина ехала нормально, разгон, расход в норме. Я поменял лямбду на контрактную и через три месяца таже байда. Я забил на год на это дело потому что никаких иных симптомов у машины не было. Наконец через почти три года решил потушить … чек, заказал оригинальную лямбу. перед сменой лямбды сам считал сканером ошибки, итог – Р0031,Р0037,Р0136. Сменил лямбду, стер ошибки – чек погас. Но сканер выдает Pending trouble codes – P0030, P0037. Я честно сказать в замешательстве. Перед сменой лямбды чистил дроссельную заслонку, менял свечи. Хэлп!

Васильич32:

У меня хоть и ФФ3, но лямбду мне ОД тоже приговорил к замене, причем цену озвучил в 13000р. за штуку, а мне рекомендовал заменить 2.   Денег я этим упырям решил не давать, а покурил форум, купил датчик от Калины-малины и вчера самостоятельно его заменил. Машина полетела, блин.   Она у меня сроду так не ехала.   Сначала обкатка была, не погоняешь, а когда обкатка кончилась видно датчик уже не жилец был. Правда чек пока не погас, но буду надеяться, что погаснет.

Мужики, а помогите мне тоже. Машина притупливает, (сразу скажу, знаю как она должна ехать, сейчас она притупливает) сменил свечи, не изменилась. Двигатель 1,8. На прогретой машине мгновенный расход пишет 1.1 литров в час (обычно 0,8-0,9 писал). На тот момент был в Минске, далеко от дома, скатался до оф дилера, подключили сканер, ошибок нет, но вот 2 лямбды.. Второй график почти похож на первый. Т.е. Катализатор я так понимаю в очистке не учавствует? Но и ошибок нет и джеки чана нет. Как поступить?
